A fire ripped through a University Avenue apartment building on West 195th Street and Eames Place on Sept. 13, injuring 14 residents, three of whom are in critical condition.

Residents described terrifying moments trying to flee on fire escapes that were hard to find in poorly lit, smoke-filled areas. Below a shattered fifth-floor window, a trail of blood stained the building. It was from a resident who severed an artery while trying to escape.

The fire began in a second floor apartment after 11:15 p.m on Wednesday in the northwest Bronx. A 4-year old girl, 34-year old woman and 50-year old man are in critical condition at North Central Bronx Hospital and New York Presbyterian Hospital.

Thick smoke traveled quickly and filled the poorly designed apartment units, making it difficult for residents to find fire escapes. “That was the worst several minutes in my life,” said Jeimy Diaz, a resident in the fifth floor who injured herself while trying to find the fire escape atop the darkly lit roof. “We thought we were gonna die. The whole building is damaged.”

The fire department could not be reached for comment. DNAinfo.com reported 25 fire units, more than 100 firefighters, rushed to battle the blaze inside the six-story building.

The Brooklyn-based landlord, Residential Management Inc., has received 93 complaints this year from residents of the building, according to city records. The complaints range from broken windows, water leaks, mold and defective or missing smoke detectors.

Charred furniture, strewn belongings and broken glass replaced what were once living spaces for many residents.

While the cause of the fire is still under investigation, residents such as Diaz are asking to be relocated. She worries that her children who have asthma will suffer from the lingering chemicals that now rise from the building’s physical damage.

Ryan Hernandez, 12, lives on the first floor and was able to immediately evacuate the burning building. “I didn’t know what was happening,” said Hernandez, “people were screaming and I heard the firemen say ‘get out there! Everybody get out.’”
